Help me. Viewsonic XG270 vs Asus VG279QM

[nanoBarre]

Hello, I have read this forum in these weeks because I am in search of a 240hz monitor.
I have concluded on these two options (Asus VG279QM vs Viewsonic XG270), but I can't decide which one.
I want to take advantage of the 240hz. Which of these two monitors performs best at that refresh rate? Is there a noticeable difference to the human eye regarding input lag or response time between one and the other?
Which one has less ghosting at 240hz? Is that ghosting difference noticeable?
The use of the monitor is focused for fps games.
I would like to hear your opinion and experience, I am a beginner in the matter.


Sorry for my bad English. Greetings from Argentina, and thanks for your time.
